United Kingdom is a developed country and  was  the first industrialized country in  the  world. There are lot of sightseeing places in London. Amongst River Thames, London Bridge, Buckingham palace, Madame Tussaud etc were good. I was amazed to see the 11 colour coded London Tube map. Most of them are underground and very old. We travelled most  of  the  time by  the London tube. Most of  the  circles are  named  as  circus.
Europe consists of approximately 50 Countries. We had covered Belgium, Netherlands, Germany, Italy, Vatican City, Austria, Switzerland and France. It is so far the BEST trip of our lifetime. An incredible group was the main
reason of most pleasant trip.
